[Lvas] Few more pics

Fred.

 

A 4-inch Unitron was large indeed. Mallas had a mechanical weight driven clock drive in a massive bell shaped pier. I have never looked through one. 

 

Skiff and Luginbuhl could also see the dark region easily in a 60mm refractor from a rooftop observing platform atop the chemistry building on the Northern Arizona University campus in Flagstaff at 35°.2. This is almost identical to my latitude here in Boiling Springs NC.

 

My notes indicate that I have never observed M-64 with my 4-inch. I will put this on my list.

Another observing challenge.

 

Fred, I will not have my notes on the Virgo cluster complete until tomorrow or Tuesday. Will this be Ok? All of this observing and staying out till 2 or 3:00 AM has got me behind, and tired. 

 

I have got to get in the bed after last night.

Roger,
 
I can understand how Mr. Mallas saw the dark region back then. Light pollution was not near what it is now. I also suspect his optics were much better in that Unitron. I remember that 4" monster being a hit or miss thing, especially for the price back then. However, most I looked through (3, I think) had very decent optics and with the f/15, those lenses didn't have to be all that thick. Correction was also much better. I'd heard from a couple of people that there were a few crap scopes out there, but not that often.
 
The Unitron 4" is an absolute monster and is mainly an observatory scope. I remember some of them were bristling with five or six finders and guide scopes that were pretty much useless!

Jay and Annette,
 
I am certainly enjoying your images. M-64 is especially interesting to me as on nights of less than excellent seeing I cannot see the dark region with my 10-inch.
 
John Mallas of the Messier Album "could see the dark region with a 60mm refractor and found it easy in his 4-inch Unitron f/15 refractor but subdewed in an 8-inch". (1958-1962)
